What is more serious is that once the coal dust in a coal dust explosive mine exceeds the standard, it will cause an explosion accident when encountering a fire source or high temperature, and the consequences are disastrous. At present, most of the underground coal mines usually use manual water sprinkling or automatic spray devices to spray dust reduction.
